摘要:
One embodiment of the present invention relates to a method for transmitting control information by a base station, comprising the steps of: transmitting data through a physical downlink shared channel (PDSCH); and receiving a receipt acknowledgement in response to said data in the 4th subframe following the subframe in which said data is transmitted. When downlink control information that indicates said PDSCH is transmitted in a resource region not including a resource indicated by a physical control format indication channel, the downlink control information is transmitted in kth subframe prior to the subframe in which the PDSCH is transmitted.

Disclosed is a method for transmitting a downlink control channel by a base station in a wireless communication system. More particularly, the method comprises the following steps: setting a transmission resource for transmitting the downlink control channel in a data area of a subframe; mapping one or more first control channels for downlink acknowledgement(ACK)/negative-ACK(NACK) information to the transmission resource; and transmitting the mapped one or more first control channels, wherein the one or more first control channels are mapped to a location adjacent to a terminal specific reference signal existing in the transmission resource.

A method for transmitting uplink signals from a user equipment to a base station in a time division multiplexing wireless communication system is disclosed. The method comprises the steps of transmitting a first uplink signal on an uplink subframe or a special subframe that precedes the uplink subframe, by preceding a first timing advance value at a reference time; and transmitting a second uplink signal on the uplink subframe by preceding a second timing advance value at the reference time, wherein the first timing advance value is greater than the second timing advance value, and the first uplink signal is transmitted for an uplink pilot time slot (UpPTS) period of the special subframe if a difference value between the first timing advance value and the second timing advance value is greater than a preset value.

The present invention relates to a method in which a UE estimates a downlink data channel in a wireless communication system, and an apparatus for the same. Specifically, disclosed is a method in which a UE estimates a downlink data channel in a wireless communication system, the method including the steps of: receiving a downlink control channel using a UE-specific reference signal; bundling a resource block for a downlink data channel into one channel estimation unit when a space resource for the downlink control channel and a space resource for the downlink data channel which makes commands in the downlink control channel are the same as each other; and performing a channel estimation on the basis of the UE-specific reference signal with respect to the one channel estimation unit.

The present invention relates to a method for transmitting a terminal-specific reference signal for a control signal by a base station in a wireless communication system. Specifically, the method is characterized in that it comprises: transmitting a plurality of control channels and a first terminal-specific reference signal for the plurality of control channels to a first resource region; and transmitting one control channel and a second terminal-specific reference signal for the control channel to a second resource region, wherein the different descrambling identifiers are applied to the first and second terminal-specific reference signals.

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus for reporting channel state information (CSI), wherein the method in which a terminal reports CSI comprises the steps of: receiving configuration information for periodic CSI reporting from a base station; and transmitting CSI information for each of a plurality of sets of CSI reports based on said configuration information to said base station via a physical uplink control channel (PUCCH). Said plurality of sets of CSI reports contains one or more mutually different subframes.
